fantasai,

not quite an answer to what you're requesting, but had you considered  
how CSS drop shadows will be implemented in SVG? including SVG fonts  
I guess?

my concern being that the absence of 'border's in SVG creates  
significant accessibility barriers for authors and viewers. whilst it  
is true there are a multiplicity of possibilities, this would have  
been a good place to start, had it been included. as it is it's  
extremely rare to find any visual indication of focus in the wild.

could CSS drop shadows help?

I'm working on the CSS3 Backgrounds and Borders [1] module with Bert  
Bos, and
I'd like to start a new Q&A series because I think we need some help:  
This
time I'll ask the questions, and you give me answers. Ok? :) The first
issue is a complicated one, so I'll start with an easy question. The  
topic
is drop shadows.

In the latest public working draft [2] we have a <code>box-shadow</ 
code> [3]
property. The point is, obviously, to be able to draw a drop-shadow  
for a
CSS box. It starts to get complicated once you ask "what happens when  
there
are semi-transparent parts of the box?" At first we figured 'box-shadow'
should just draw the shadow as if the box was opaque. Then Dave  
Hyatt, who
had started implementing this, started questioning that logic. We've got
proposals for a 'border-shadow' property to shadow just the border and a
'background-shadow' property to shadow just the background color (but  
not
the image?), etc. We could also just "shadow everything drawn in this  
element".
This all sounds rather complicated to me so I want to step back and ask:

What do you, as a web designer, want to *do* with shadows? What's the  
end
result you want to get?

Show me. Post a few links to stuff from your portfolio that uses  
anything
beyond pure text shadows, even if it's all done with pure Photoshop(/ 
Painter/GIMP)
graphics. Draw (or explain) a picture of what you want to achieve. Then
maybe we can figure out how best to make it happen in CSS.
